Description

Device for catching and killing larva of Apis cerana Fabricius
Technical Field
The invention relates to a device and a method for killing a apis cerana, in particular to a device and a method for killing apis cerana in larva stage.
Background
Chinese bees (Apis cerana cerana Fabricius, called Chinese bees for short) are special bee genetic resources in China and are listed in a national-level livestock and poultry genetic resource protection directory. The hornet (Syntretomorpha szaboi Papp) is one of the most prominent parasitic wasp diseases that currently endanger middle bees, and is used for larval endangering adult bees in the middle bee colony. The Apis cerana is mainly distributed in the eastern ocean area, and since 1973, apis cerana is found in Guizhou (identified as Apis cerana), so far, guizhou, shanxi, chongqing, hubei, sichuan and Taiwan all have harmful reports, and the parasitic rate of the worker bees in the bee colony can reach about 20%, so that the development of the Apis cerana industry is seriously affected.
The Chinese bees are parasitic by the hornet of the hornet, and the parasitic rate of the bee colony with more young bees is high no matter how strong the bee colony is. The spreading of the apis cerana is mainly carried out by the ways of adult flighting, swarm transferring, beehive exchanging and the like. At present, the bee raising in China mainly adopts the ground-turning 'flower-chasing and honey-capturing', the fluidity of the bee colony is very strong, and the parasitic bees are not included in the bee inspection and quarantine category, if the parasitic bees are not prevented, the bees in the whole middle bee area in China are transmitted and endangered, and immeasurable losses are caused.
The genus Apis (Syntretopora) belongs to the subfamily Hymenopterae of the family Hymenopteridae, which is a lesser class, and only one species, namely, apis cerana, is recorded in China. The Apis cerana Fabricius undergoes four stages of eggs, larvae, pupae and adult bees, the Apis cerana Fabricius undergoes eggs and larval stages in the abdominal cavity of Apis cerana Fabricius (figure 1), pupae are drilled out of the body of Apis cerana Fabricius (figures 2 and 3) after larva maturation, adult bees are finally developed, and after mating, offspring are spawned and propagated at the abdomen of Apis cerana Fabricius. The Apis cerana Fabricius occurs for about 3 generations in one year, and wintering with pupa occurs mainly in the period of 4-10 months. After mating, the female bees of the apis cerana hance are allowed to move inside and outside the bee colony, suitable worker bee hosts of the apis cerana hance are searched, and after the targets are found, the worker bee hosts immediately follow the attack and spawn. The female bees of the apis cerana of the worker bees are penetrated into the internode membranes between 2 and 3 sections of the abdomen by using the ovipositor, each middle bee spawns 1 (2 is rare), eggs are hatched into larvae, the larvae feed in the interior of the worker bee body by sucking the body fluid of the bee, and the like, after the larvae develop and mature, the larvae bite through the abdomen of the Chinese bees and climb out of the body wall (figure 4), then quickly find proper gaps, stone gaps or places such as soil in the bottom of the beehive to pupate (figure 5), and then emerge into beehives. The period from 1-2 generation eggs to larvae of the Apis cerana Fabricius is 36-39 days, the period from cocoon setting to emergence is 11-13 days, the adult bee life is more than 30 days, the pupa period of the 3 rd generation is longest, and the Apis cerana Fabricius leaves from 10 months to 4 months of the next year. The Chinese bees have no obvious symptoms in the early stage of parasitic growth, can normally dry and live, but the carried pollen and nectar amount can be reduced, when the larva of the Apis cerana Fabricius is mature, a large amount of parasitic worker bees can leave the spleen, lie on the six feet tightly, and lie on the bottom, the inner wall or the nest door pedal (figures 6, 7 and 8) and other places. The parasitic worker bees had slightly larger abdomen, lost flying ability, the stings could not be stretched and the person was not stined, and after dissecting, larvae of the hornet were clearly seen in the abdomen (fig. 9 and 10). The parasitic worker bees are driven out of the bee colony by other worker bees due to abnormal conditions, but most of the worker bees are often gathered at the entrance or the bottom of the beehive, the worker bees with parasitic cocoons are fed by other worker bees and live near the nest door or the bottom of the beehive, and after the larva of the hornet of the bee is mature and climbs out, the parasitic worker bees die; some worker bees parasitizing the cocoons can live outside the beehives, but because bees live in the social life, the bees die because food cannot be obtained if the bees do not live in the social life, so that most larvae of the cocoons of the hornet cannot pupate because of immature development, and finally die. The swarm vigor damaged by the hornet of the hornet can drop sharply, and the collection emotion drops, so that the breeding of the middle bee swarm and the honey collection are seriously affected.
At present, no effective prevention and treatment measures are available for the hornet of the hornet, and the infected bee colony is generally prevented from further spreading in a destroying treatment mode. Meanwhile, in the feeding management process, the beehive is thoroughly cleaned before the end of 4 months of each year, the overwintering pupa cocoons of the apis cerana cocoons are cleaned by soil at the bottom of the beehive, the beehive is cleaned frequently at ordinary times, the survival rate of the apis cerana cocoons and pupa is reduced, adult bees of the apis cerana cocoons are timely killed, and the worker bees which are dead in the nest gate and are inactive are scalded by boiled water, so that the harm of the apis cerana cocoons is prevented and relieved. However, these methods have the following problems: destroying the bee colony, and preventing the bee farmers from losing too much and being easy to popularize; the Chinese bees are mostly cultivated in mountain areas, the bee colony is mostly placed in a mixed stone mess grass, and the cocoons of the bees of the Venetian bees are mostly avoided from pupating in the mixed stone mess grass near the beehive, so that the Chinese bees are not cleaned and are troublesome; the cocoons of the Apis cerana Fabricius and the cocoons of the wax moth-larva cocoons of the large and small wax moth in the beehive are very similar, so that beneficial wax moth-larva cocoons can be killed together easily, and the damage opportunity of the swarm of bees is increased; the worker bees which are dead in the nest gate and do not move are killed by scalding with boiled water, but the worker bees of the parasitic wasp cocoon bees are killed by the worker bees, the guard bees, the collecting bees, the fan bees, the stink bees or the separated bees, and the like, so that the colony potential is greatly reduced.
The related literature on the technology of preventing and controlling the hornet of the hornet is not much at home and abroad, and China patent 201810873348X discloses a method for separating the hornet colony from the hornet of the hornet by utilizing the behavior change of the hornet parasitic in the Chinese worker bee, and killing the worker bees at regular intervals, so that the hornet in the Chinese worker bee cannot develop to mature and cannot pupate, the generation breeding is cut off, and finally the aim of reducing the survival of the hornet is fulfilled. However, the method is complex, the prevention and control time is long, the life of the bee colony can be disturbed outside the beehive each time when the bee is shaken, particularly in the high-rise period of the cocoon bees, the outside is 7-8 months with higher temperature, most of the bee colony is broken in the over-summer period, and thus, the large-scale shaking-off bee colony is in front of the beehive door, other problems such as flying and escaping of the bee colony are easily caused, and the production of the bee colony is easily influenced.
Disclosure of Invention
The invention aims to provide a device and a method for effectively catching and killing the larva of the Apis cerana Fabricius.
To achieve the above object, the present invention is achieved by: a device for killing the larvae of the hornet cocoons of bees, which is characterized in that: including upper portion open-ended album larva box, album larva box has certain degree of depth and smoothness, album larva box sets up in the lower part of beehive, just the opening of album larva box meets with the bottom plate edge of beehive makes the outside time climbing of bee cocoon bee larva can fall into by the bottom plate edge of beehive in the album larva box.
The device provided by the invention fully utilizes the living habit of the apis cerana, pupates are carried out in a place where the apis are required to leave in the larva stage, the larva collecting box is arranged in the process of crawling the apis cerana to leave the beehive, the apis cerana larva is intercepted and collected, and the contact killing chemicals can be applied in the larva collecting box to prevent the apis cerana larva from pupating and cocooning.
Further, the opening area of the larva collecting box is larger than the area of the bottom plate of the beehive, a supporting device is arranged in the larva collecting box, and the beehive can be placed in the larva collecting box and supported on the supporting device.
Preferably, the larva collecting box is strip-shaped, the rear wall is connected with the edge of the bottom plate of the beehive, the front wall is separated from the edge of the bottom plate of the beehive, the left wall and the right wall are provided with connecting pieces which can be connected with the beehive, and the connecting pieces can serve as blocking pieces for preventing bees from climbing backwards.
For further collecting the larva of the hornet cocoon, the connecting piece is a side baffle, one end of the side baffle is connected with the left wall or the right wall of the larva collecting box, and the other end of the side baffle is connected with the body of the beehive.
Preferably, the wall of the larval box that is spaced from the floor edge of the beehive is 8-15cm from the floor edge of the beehive.
Further, a bee escape device is arranged in the larva collecting box at a position 2-4cm away from the bottom wall.
Preferably, the bee escape device is a grille arranged in the larva collecting box, the holes in the grille are long-strip holes, and the width of the short sides of the long-strip holes is 2-3.5mm.
A method for harvesting and killing the larvae of a apis cerana of a apis, comprising the steps of:
the first step: the larva collecting box is placed in the box,
when a plurality of worker bees without stings are trapped in the hive nest door, the larva collecting box is arranged at the lower part of the hive and fixed in front of the hive nest door, so that any falling objects can be caught under the pedal of the hive;
and a second step of: biological agent
Putting water, quicklime and soil mixed with Bacillus thuringiensis or traditional Chinese medicine powder into the larva collecting box to prevent the larva of Apis cerana from surviving; the traditional Chinese medicine powder is prepared by mixing 3-5 parts of capsicum, 1-5 parts of ginger, 20-30 parts of sweet wormwood, 20-30 parts of chinaberry, 1-3 parts of pepper, 1-3 parts of camphor bark, 3-5 parts of tripterygium wilfordii and 20-30 parts of tobacco leaves;
and a third step of: time of placement
The method can select the high-rise stage trapping and killing of the larva of the Apis cerana, and can select 4-10 months each year to be placed in order to prevent more larva of the Apis cerana, and all the surrounding bee fields are trapped and killed together.
If water is added into the larva collecting box, the water in the larva collecting box needs to be ensured not to be dried.
If quicklime, soil accompanied with bacillus thuringiensis or traditional Chinese medicine powder is placed in the larva collecting box, the larva collecting box is replaced once a week.
The beneficial effects are that:
the invention aims to kill the hornet of the hornet so as to reduce the forced injury to the hornet. The inventor fully researches the habit of the hornet, and selects the stage which can be most basically eliminated without influencing the hornet to collect and kill. This stage is the stage in which the apis cerana is allowed to develop from eggs to larvae but not yet pupated. Although the method has the effect on the apis cerana in the egg stage, after the apis cerana is developed into larvae, the characteristics that the apis cerana is crawled to find pupa forming sites can be utilized to collect and collect the apis cerana in the biting manner after the apis cerana is drilled out from the belly, so that the effect of basically killing the apis cerana is achieved, and the forced damage to the apis cerana after the apis cerana survives is avoided.
Specifically, there are two different life cycles for a apis cerana kanehirae cocoon bee: one is the intraperitoneal parasitic phase of the Chinese bee, and the other is the in vitro living phase. The interior of the Chinese bee worker bee body is a natural barrier for the hornet of the hornet, so that on one hand, bees and people cannot clear eggs or larvae of the hornet, and on the other hand, chemical medicine penetration is blocked, and the medicine effect cannot be exerted. The bee cocoon bee also has two periods in the bee body, one is the pupation period in different places such as grass, stone seams or soil at the bottom of the beehive, and the other is the mating and spawning period inside and outside the beehive after the beehive is developed into bees. Because the pupation of the apis cerana of the ston and the site is not fixed, and a layer of protective cocoon skin is arranged outside the cocoon shell, so that the cocoon shell can not be thoroughly removed and used by people. Adult apis cerana of the hornet are extremely difficult to kill due to flying activities inside and outside the hive. Moreover, the trapping and killing or medication of adult bees of the Apis cerana Fabricius and Apis cerana Fabricius can seriously influence the Apis cerana Fabricius. However, after the larva of the Apis cerana Fabricius is mature, the larva bites the wall of the middle bee body, drills out from the abdomen, climbs to the bottom of the hive and searches for a proper place for pupation. The method is characterized in that eggs, larvae and pupae of the Apis cerana Fabricius are only exposed for one time in three periods, namely a special period for leaving a bee colony to remove cocoons, and meanwhile, the larvae have special requirements on pupation places, namely, safe places where other organisms such as bees are not easy to directly contact, because the climbing capability of the Apis cerana Fabricius larvae is very weak after the larvae climb out of the bees, the larvae directly climb to the pedal edge of a beehive at a honeycomb gate to fall down, and the larvae are drilled into soil, grass, stone joints and the like to pupate; if the beehive is complete and has no gap, the larvae can climb at the bottom of the beehive until the larvae climb out of the nest gate and enter the pupation place; the entire process of finding the pupation site takes about 10 minutes. Therefore, the invention sets the interception device at the place where the larva of the apis cerana is pupated, and applies the contact killing chemical in the device to prevent the larva of the apis cerana from pupating and cocooning. Achieve the aim of basically using the hornet of the hornet and the effect of collecting and killing is complete.

Detailed Description
The following describes in further detail the embodiments of the invention with reference to the accompanying drawings, but the invention is not limited to these embodiments, any substantial modifications or substitutions of the present examples, still falling within the scope of the invention as claimed in the claims.
Examples: as shown in FIGS. 1-20, the present invention provides a device and method for collecting and killing the hornet of the hornet. In particular to a device and a method for collecting and killing larva stages of a apis cerana.
The device of this embodiment is a larva collection box 100 that is used in conjunction with a beehive to collect larva of a apis cerana hance reeding out of the beehive. And contact killing chemicals are applied to the bottoms of the larva collecting boxes to prevent the larva of the hornet from pupating and cocooning, so that the larva of the hornet is collected and killed.
In particular, the larval box is box-shaped with an upper opening, and has a certain depth and smoothness. The depth of the box body is designed to ensure that the larvae fall into the box body and cannot fear to climb out, and proper chemicals or water are required to be applied in the box body.
The opening of the larva collecting box needs to be guaranteed to cover the edge of the bottom plate of the beehive, so that the larva which climbs out of the edge of the bottom plate of the beehive can fall into the box body. In this example, two implementations are provided.
First, see figures 11 and 12, the open area of the larval box is larger than the area of the floor of the beehive. And set up strutting arrangement in album larva box, strutting arrangement 103 sets up the middle part in the album larva box is apart from the box bottom surface a distance, the beehive can place strutting arrangement is last. The side walls of the larva collecting box are at a certain distance from the edge of the bottom plate of the beehive, so that all the larvae climbing out of the beehive fall into the larva collecting box. And under the support means, a suitable chemical or water ensures that the larvae falling into it are killed.
The shape of the opening of the larva collecting box is consistent with the shape of the bottom plate of the beehive, and each side wall of the larva collecting box and the edge of the bottom plate of the beehive are provided with a distance of about 10 cm. The depth of the larva collecting box is 10cm, the supporting device is arranged at a position 5cm away from the bottom surface of the box body, and water or chemical medicines are applied at or below 3cm away from the box body.
The supporting device can be a supporting plate arranged on the inner side wall of the box body, and can also be a supporting net arranged in the middle of the box body.
The second is shown in fig. 13 and 14, the larva collecting box is strip-shaped, the rear wall is connected with the edge of the bottom plate of the beehive, the front wall is separated from the edge of the bottom plate of the beehive, and the left wall and the right wall are provided with connecting pieces which can be connected with the beehive.
Wherein the connection piece also serves as a side shield 101. The larva collecting box is matched with the beehive for use, and the larva collecting box is arranged in front of a nest door of the beehive, so that the rear wall of the box body is contacted with a bottom plate at the nest door of the beehive. One end of the side baffle is connected with the left wall or the right wall of the box body, and the other end of the side baffle is connected with the body of the beehive. And the side baffle plates and the rear wall are provided with flanges which are used for connecting and fixing the box body and the beehive through drawing pins and the like. And the rear wall of the larva collecting box is provided with a mounting hole for mounting a cross rod arranged at the bottom of the bottom plate of the beehive, so that the rear wall of the larva collecting box is tightly attached to the edge of the bottom plate of the beehive.
The wall of the larval box that is spaced from the edge of the bottom of the beehive is 8-15cm from the edge of the bottom of the beehive, optionally but not limited to 8cm, 9cm, 10cm, 11cm, 12cm, 13cm, 14cm or 15cm. In this embodiment, the front wall of the box body is 12cm from the edge of the bottom plate of the beehive (at the nest door). The length of the larva collecting box is slightly longer than that of the bottom plate of the beehive, so that the retaining edge is convenient to set. The depth of the box body is 7cm, a bee escape device is arranged in the box body at a position 3cm away from the bottom wall, and the escape device is higher than chemical medicines or water applied in the box body. The bee escape device in this embodiment is a grille 102 disposed in the larva collecting box, the holes on the grille are elongated holes, and the width of the short sides of the elongated holes is 2-3.5mm, which can be selected but not limited to 2mm, 2.5mm, 3mm or 3.5mm.
Because the larva of the hornet essentially climbs out from the hive entrance, a second larva collecting box can be arranged at the hive entrance to collect and kill the larva climbed out. Of course, the second larva collecting box can be tried around the bottom plate of the beehive, and the first larva collecting box can also be directly adopted.
And set up the grid in the box body of larva collecting box, even the honeybee falls into the box body carelessly, also can not fall into chemicals or water, can directly fall onto the grid to can fly out and flee.
In addition, the embodiment also provides a method for collecting and killing the larva of the Apis cerana Fabricius, which comprises the following steps:
the first step: box for placing larvae
When a plurality of worker bees without stings are trapped in the hive nest door, the larva collecting box is arranged at the lower part of the hive and fixed in front of the hive nest door, so that any falling objects can be caught under the pedal of the hive;
and a second step of: placing into biological agent
Putting water, quicklime and soil mixed with Bacillus thuringiensis or traditional Chinese medicine powder into the larva collecting box to prevent the larva of Apis cerana from surviving;
wherein the traditional Chinese medicine powder is prepared by mixing 3-5 parts of chillies, 1-5 parts of ginger, 20-30 parts of sweet wormwood, 20-30 parts of chinaberry, 1-3 parts of pepper, 1-3 parts of camphor bark, 3-5 parts of tripterygium wilfordii and 20-30 parts of tobacco leaves according to weight parts;
and a third step of: time of setting device
The method can select the high-rise stage trapping and killing of the larva of the Apis cerana, and can select 4-10 months each year to be placed in order to prevent more larva of the Apis cerana, and all the surrounding bee fields are trapped and killed together.
In addition, if water is added into the larva collecting box, the water in the larva collecting box needs to be ensured not to be dried. If quicklime, soil mixed with bacillus thuringiensis or traditional Chinese medicine powder is placed in the larva collecting box, the larva collecting box is replaced once a week.
In a specific implementation process, the use condition is as follows: in the high-rise period of the larva of the apis cerana hance in the Chongqing area of 2019, the number of worker bees with the most gate of the beehive is up to 119 (figure 15), and we select to place larva collecting boxes at more than 10 nest gates on average, wherein 5.17+3.73 larva of apis cerana hance are collected every day in each box, and the details are shown in table one and figures 16-20.
The number units of the larva of the Apis cerana Fabricius collected by the epizootic larva box are as follows: only
